We have found that a superior kind of artificial horn may he produced from casein by incorporation therewith of liquid or solid hydroaromaticor 1 aliphatic-hydroaromatic 5 amines, or such aliphatic amines as contain hydroxyl groups, or of salts or derivatives of a the same.

Such aliphatic-hydroaromatic amines as contain hydroxyl groups are, inter alia, particularly'suitahle, as for example, cyclohexylethanolamine, cyclohexyldiethanolamine 1 and homolo'gues thereof. Substances of this kind possess especially the property of facilitatingthe plastification and clarification of 1 casein to an extraordinary degree. These properties are manifested even at ordinary temperature, if moistened casein he intimately mixed for example with a small percentage of cyclohexylethanolamine; thereby the conversion of the casein into a plastic can be obtained under comparatively low pressure and 1 at moderate temperature. The acyl derivatives of the beforementioned amines, such as formyl or acetyl-compounds, for example, formylethanolamines as are obtained by the action of ethylene oxid' on formamide, are also applicable for the purpose required. In many instances, salts of the said amines, such as carbonates, acetates 0 and lactates, are also applicable with advantage, cyclohexylamineacetate' for example, forming a suitable agent.-

I Manyof the specified amines, theirs'alts f and derivatives such as acyl com ounds, are soluble in water, a feature which greatly facilitates their application for the purposes" of this invention;

The following example yvill furtherillustrate the nature of the said invention which V however is not limited thereto.

Example the mass being intimatelmixed. The further treatment is eifected y moderately heating under pressure in'any known or suitable manner, and an excellent artificial horn is obtained.

The eyolohexylmonoethanolamine may our hands. 7
